2.2Theory of Operations
The EQ PU20 Digital Peristaltic Dispenser transfers low viscosity liquids by pressure displacement
applied by a turning rotor against a tube carrying the material. Usually these pumps are chosen
because the liquids are hazardous or difficult to work with and it is advisable to limit operator
contact. Another reason is that peristaltic pumps are air free.
Dispense outputs can be timed from 0.01 - 99.99 seconds with flow speeds from 0.01-6 ml/min
using PTFE tubing. The pump is bi-directional allowing suck-back after dispense to prevent
dripping of the fluid. When dispensing UV adhesives use only black tubing. This avoids curing of
the adhesive in the tube.
The amount of product dispensed is controlled by:
Dispensing time
Feedline size
Motor speed
Needle size
Various sizes of PTFE tubes, the corresponding applicator nozzles and dispensing needles are
available, see section 5.1
